The Pokémon Go craze peaked a little over a year ago. Economists have since had time to crunch some numbers:

A review of accident reports in an Indiana county found that 148 days after the game was released there were $5 – $26 million in damages from car crashes, likely as a result of people playing the game while driving.

This includes two lost lives. Scale that across the United States and you get damages as high as $7.3 billion.

Crashes were particularly high around Pokéstops – places where people could go to stock up on virtual supplies.

The game did take some steps to prevent this. Players who were moving too fast were blocked from battling in gyms.

Tinder is a big reason why. NBA players on the road now get a lot more sleep as they don’t need to stay up all night drinking at clubs to pick up dates.

Instead by texting their date and leaving a key at the front desk, they can have someone in their room waiting for them the moment they return to their hotel.

The rise of chartered jets – where coaches can control diet and alcohol intake – has also boosted sleep levels.

Social media in general now allows the world to see if players are up late before a game, or in a drunken brawl. To protect their brands and corporate sponsorships players have decided it’s better to just stay in.

Voyagers like Christopher Columbus and Amerigo Vespucci found distant continents – and in the process forced European mapmakers to deal with the vastness of the oceans.

Often they would shrink the size of the Atlantic ocean – making the new world seem much closer than it really was.

Some were outraged by the scarcity of land in the southern hemisphere – and reasoned that there must be an undiscovered continent in the south, which they called “Terra Australis Nondum Cognita” – southern land not yet known (see image above)

When Europeans ran into Australia they assumed that this was the fabled southern mega-continent, thus explaining how Australia got its name.

The oceans could be used for branding purposes. Mapmaker André Thévet, for example, names a series of non-existent islands after himself in the ocean.

One Venetian nationalist littered the vast oceans with Venetian galleys – entirely unsuited for trans-oceanic travel, but propagating what was, by that point, the myth of Venice’s pre-eminence.
